Adam Greenberg: The story of Greenberg's one-game career with the Cubs is infamous. Greenberg was hit in the head with the first pitch he saw after being called up in 2005, and had only a token appearance in the majors again. The Cubs rejected overtures to sign him last year to give him one more at-bat. The Marlins did and he struck out. Greenberg is in the Orioles' camp now, attempting a comeback.
